R 所有数据集中最常用的单词

我的数据集如下：

interests<-data.frame(interests=c("A mentor/teacher,Friendship",
                      "A play partner,Princess by day slut by night,Friendship,A sub,A slave",
                      "A relationship,A play partner,Friendship,Events",
                      "Not Defined"))

interests
<fctr>
A mentor/teacher,Friendship
A play partner,Princess by day slut by night,Friendship,A sub,A slave
A relationship,A play partner,Friendship,Events
Not Defined

或者，因为你似乎认为“游戏伙伴”一个词：
table(unlist(strsplit(as.character(interests$interests), split=",")))
